    Introduction The 9600 Series IP Telephone product line uses Internet Protocol (IP) technology with Ethernet interfaces. The IP telephones supplement the existing Avaya IP Solutions platform. The 9600 Series IP Telephones support DHCP and HTTP/HTTPS over IPv4/UDP which enhance the administration and servicing of the telephones. These telephones use DHCP to obtain dynamic IP Addresses and HTTP or HTTPS to download new software versions or customized settings for the telephones.
